A primary intrapulmonary left-sided thymoma is described in a 23-year old man. Eight similar observations can be found in the world literature. The histology is quite uniform. The tissue shows characteristic epithelial and lymphatic cellular elements but organoid differentiation into medullar and cortex is lacking. Hassall's granules are only rudimentary. Giant cells in all stages of development, tissue mast cells, varied supporting tissue, epithelial border layer and connective tissue capsule are all present. There is no blastomatous degeneration. Theoretical indications to explain the sudden onset of tendency to proliferation of the ectopic thymus independant of age and sex are discussed.
本文描述了一名23岁男性原发性肺内左侧胸腺瘤。世界文献中可找到8例类似病例。组织学表现相当一致。组织显示出特征性的上皮和淋巴细胞成分，但缺乏向髓质和皮质的类器官分化。哈氏小体仅发育不全。各个发育阶段的巨细胞、组织肥大细胞、多种支持组织、上皮边界层和结缔组织包膜均存在。无母细胞瘤变性。讨论了解释异位胸腺增殖倾向突然发作且与年龄和性别无关的理论依据。
